The prevalence of Staphylococcus aureus carriage among healthy children from four kindergartens located in the North of Portugal and antibiotic resistance of the isolates were evaluated. Nasal swabs were collected from 296 healthy children aged 3 to 6 year. 144 were carriers of S. aureus; 15% of the strains were multidrug resistant. Resistance to gentamicin, chloramphenicol, rifampicin, oxacillin, nitrofurantoin, tetracycline, erythromycin, ampicillin and penicillin were determined to be 1.5, 2.2, 2.2, 9.7, 19, 34.1, 73.3, 84.4 and 91.1%, respectively. All the strains were sensitive to vancomycin. Our study reveals a high prevalence of healthy children carrying S. aureus (49%), including MRSA (9%), in the nasal cavity.
